An automated system and method for determining the value of an intangible asset or intellectual property and developing a fair remuneration structure for licensing or purchasing the intangible asset or intellectual property by comparison to a dissected database of prior licensing and sale transactions. Valuation determinants and remuneration structures from prior transactions are extracted, analyzed and weighted and loaded into a knowledge base. Remuneration structures are normalized and used to train predictive algorithms based on a market analysis of previous transactions. The algorithms are able both to learn from previous transactions and to assess the importance of particular valuation determinants in determining the value under particular circumstances. An equitable rate for a new transaction is determined by examining the knowledge base and varying the valuation determinants. An optional expert system and dynamic modeling environment are provided.

The integration interval is at least part of a high-level interval and a low-level interval of the pulse signal.

An apparatus and method for inverting a 4×4 source matrix. A source matrix is divided into four 2×2 sub-matrices. A plurality of sub-matrix products are subsequently calculated from the sub-matrices. Next, a determinant of the source matrix is calculated to form a determinant residue utilizing the previously computed sub-matrix products. Calculation of partial inverse for each sub-matrix is next performed, using the sub-matrix products and determinants of the sub-matrices. Finally, an inverse of each sub-matrix is calculated, utilizing the partial inverse sub-matrices and the determinant residue to form an inverse of the 4×4 source matrix. The article allows processors to store two floating-point elements within a Single Instruction Multiple Data (SIMD) register. Accordingly, a sub-matrix is represented using two SIMD registers, resulting in improved computational locality and efficiency. Other embodiments are described and claimed.

A continuous method for preparing proteosome-amphiphilic determinant vaccines for parenteral or mucosal administration using diafiltration or ultrafiltration technology. The amphiphilic determinants include lipopolysaccharides from gram negative bacteria, e.g. S. flexneri, P. shigelloides and S. sonnei. Proteosomes are obtained from group B type 2b meningococci. The active proteosome-amphiphilic determinant complexes (non-covalent complexes) of the vaccine are formed using diafiltration or ultrafiltration to remove the detergent under non-static conditions. The use of diafiltration or ultrafiltration decreases processing time and the opportunity for contamination and further permits the use of ambient temperature and efficient scale-up. In addition, the process permits the reliable and continuous monitoring of the dializate which enhances the efficiency of the entire process. The time of dialysis for the production of a lot of vaccine is reduced from 7-10 days to less than 72 hours and usually less than 48 or 24 hours. The use of the process optimizes the presence of each antigenic component in the preparation of multivalent vaccines.

A method useful for the enumeration of cell populations in a biological sample includes the steps of reacting in a single reaction mixture a sample, a first antibody labeled with a fluorochrome having a first emission spectrum and an additional antibody. The first antibody binds to an antigenic determinant differentially expressed on leukocytes and non-leukocytes. The additional antibody binds to an antigenic determinant differentially expressed on mature and immature granulocytes or myeloid cells, and is labeled either with the first fluorochrome or an additional fluorochrome having an emission spectrum distinguishable from the first emission spectrum. The reaction mixture can be mixed with a nucleic acid dye having an emission spectrum that overlaps with one of the first or additional emission spectra. The reaction mixture may be treated with a lytic system that differentially lyses non-nucleated red blood cells and conserves leukocytes. Populations of hematological cells are detected and enumerated using at least two parameters (fluorescence, optical, and electrical) for each population.

Antibiotics (Abx) are the world's most misused drugs. Antibiotics misuse occurs when the drug is administered in case of a non-bacterial infection (such as a viral infection) for which it is ineffective. Overall, it is estimated that 40-70% of the worldwide Abx courses are mis-prescribed. The financial and health consequences of Abx over-prescription include the direct cost of the drugs, as well as the indirect costs of their side effects, which are estimated at >$15 billion annually. Furthermore, over-prescription directly causes the emergence of Abx-resistant strains of bacteria, which are recognized as one of the major threats to public health today. This generates an immediate need for reliable diagnostics to assist physicians in correct Abx prescription, especially at the point-of-care (POC) where most Abx are prescribed. Accordingly, some aspects of the present invention provide methods using biomarkers for rapidly detecting the source of infection and administrating the appropriate treatment.
